The EAC Network, a project of the Pennsylvania Environmental Council, has compiled three watershed ERIs to be used as a tool for municipalities and EACs. The first Watershed ERI to be put on-line documents important features for watershed planning in the Upper Perkiomen Watershed, which covers parts of Montgomery, Bucks, Lehigh and Berks Counties.

The ERI is an interactive map run with SVG viewer that allows visitors to this website to select the layers they want to focus on along with a choice of background. These layers can be viewed individually or in combinations depending on what the user wants to determine. Political boundaries and natural features are displayed on this map. Streams, lakes, floodplains and wetlands are mapped because these features are so important to planning decisions. The map also includes large regional parks offering exceptional scenic and recreational value to the area.

The Upper Perkiomen watershed encompasses over 144 square miles and at least 24 local municipalities fall at least partially in the Upper Perkiomen watershed. With watersheds of this size, a strategic regional approach is necessary to enhance and maintain the quality of the watershed as a whole. EACs, municipal officials, planning commissions, land trusts, and watershed associations will be able to use this information to make more educated planning decisions, improving the overall quality of the watershed.

The information from this ERI will be accessible from several websites including the EAC Network Website, the Upper Perkiomen Watershed Coalition website and others. If you are having trouble accessing the information on this website, you may need to view a simpler version of the maps as explained on the website.

This project is one of 3 watershed ERIs conducted by PEC. The other ERIs include Pine Creek in Allegheny County, and the Darby Creek, in Chester, Montgomery, Delaware and Philadelphia counties. Data from these projects can be obtained by contacting PEC. This project was supported by Pennsylvania's Department of Environmental Protection through a Growing Greener Grant.
